WICKETeGATE-ADJUSTING MEANS.

nppiieation sied october i7, 192i.

T all whom t may concern Be it known that l, MAX HAnnnRLEiN, a citizen of the United States, residing at Maplewood, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Wicket-GateAd justing Means, fully described and represented in the following specification and the accompanying drawings, forming a part of l@ the same.

This invention relates to improvements in adjusting mechanism, and particularly to' mechanism for adjusting the wicket gates of hydraulic turbines in proper relation to their l5 operating devices.

In a hydraulic turbine, it is common to provide a series of wicket gates which serve not only to determine the amount of water supplied to the runner but also when open either wholly or partly to guide the water in a proper direction to the runner. In order that these wicket gates may be simultaneously adjusted, it is necessary to connect all the gates to a common operating device, which may then be operated either by hand or by a suitable governor mechanism.

lIn such an arrangement it is important that the respective gates shall have a correct relation to the common operating device, in order that all the gates shall close simultaneously or that when partly opened all of them will have the same angular relation to the runner. Slight difference in this angular relation may cause a considerable variation in the efciency of the turbine. To obtain this accuracy of setting with gates and connecting mechanism of a Xed or not adjustable type, great care in construction is necessary. To avoid such refinements in workmanship which, of course, involve considerable expense, attempts have been made to provide adjustable connections between the gates .and their common operating device, but the means heretofore provided have introduced difficulties of their own in that they either introduce new points of wear leading to errors of setting of the gates, or cannot be quickly and easily adjusted with certainty t`o any desired extent, but must be carefully adjusted with great skill and frequently by repeated trials.

The object of this invention is ,to ,provide 4an adjusting mechanism whereby. nol new Serial No. 508,079.

wearing point will be introduced and whereby the adjustment may be quickly made to any desired extent.

llith the above general object in view the invention consists in the features, details of construction and combination of parts which will be described in connection with the accompanying drawings, and then more particularly pointed out.

In the drawings,-

Fig. l is a detail view, partly in plan and partly in section of one type of hydraulic turbine, with the invention applied to it;

Fig. 2 is a sectional view on the line 2 2 i C the wicket gates, D the gate spindles to` which the respective gates are suitably secured, and E an operating device common to all the gates. In this case the common operating device .is shown as a ring arranged to be shifted singularly by an operating rod F which leads to suitable rod shifting mechanism generally governor controlled but capable of manual operation. The rod shifting mechanism is not shown, as it may be of any well known construction and is unnecessary to a full explanation of the invention.

Between each gate spindle D and the common operating device E is a connecting mechanism comprising an arm G having one end pivotally connectedJ tov a link H which in turn is pivotally connected to the operatmechanism., The other end of the arm is provided with a recess arranged to fit the cylindrical .upper end of the corresponding gate spindle D. @n the side of the gate spindle opposite the arm G is a yoke G1 which is secured against angular movement relative to the spindle and has each end connected tothe corresponding arm Gr by an adjustable tension device. In the embodiments of the invention shown in the drawings, the yoke is provided with a recess fitting tightly against the cylindrical surface lof the4 gate spindle, and secured against anfixed against angular movement relative to its respective spindle, and means for adjustably connecting each device to its respective arm, whereby the arm may be held in fixed yet adjustable relation to its spindle.

5. The combination, with a series of Wieket gates and their spindles, a plurality of arms, one for each gate, each arm being in contact with its spindle, a yoke for each arm, and means for fixing each yoke against angular movement relative to the spindle, of a pair of bolts for each arm and yoke, said bolts being angularly adjustable relative to their respective yoke and arm and being arranged to draw the corresponding yoke and arm toward each other and in close Contact with the shaft, said bolts being arranged one on each side of the shaft, and means pivotally Connected to each arm for simultaneously operating all the arms to adjust the gates.

In testimony whereof, I have hereunto set my hand.

MAX HAEBERLEIN.
